Types ¶
type Transaction ¶
type Transaction struct {
Version int32
Flag int32
Locktime uint32
Inputs []*TxInput
Outputs []*TxOutput
}
Transaction defines an elements transaction message.
func NewTx ¶
func NewTx(version int32) *Transaction
NewTx returns a new elements tx message. The return instance has no transaction inputs or outputs. Also, the lock time is set to zero to indicate the transaction is valid immediately as opposed to some time in future.
func NewTxFromBuffer ¶
func NewTxFromBuffer(buf *bytes.Buffer) (*Transaction, error)
NewTxFromBuffer deserializes the given raw transaction in bytes and returns an instance of *Transaction.
func NewTxFromHex ¶
func NewTxFromHex(str string) (*Transaction, error)
NewTxFromHex deserializes the given transaction in hex format and returns an instance of *Transaction.
func (*Transaction) AddInput ¶
func (tx *Transaction) AddInput(ti *TxInput)
AddInput creates an input with the given hash and index and adds it to the transaction.
func (*Transaction) AddOutput ¶
func (tx *Transaction) AddOutput(to *TxOutput)
AddOutput adds an output to the transaction.
func (*Transaction) Copy ¶
func (tx *Transaction) Copy() *Transaction
Copy creates a deep copy of a transaction so that the original does not get modified when the copy is manipulated.
func (*Transaction) HasWitness ¶
func (tx *Transaction) HasWitness() bool
HasWitness returns wether the transaction contains witness data
func (*Transaction) HashForSignature ¶
func (tx *Transaction) HashForSignature( inIndex int, prevoutScript []byte, hashType txscript.SigHashType) ([32]byte, error)
HashForSignature returns the double sha256 hash of the serialization of the transaction in order to then produce a signature from it. The transaction is serialized in a different way depending on the hashType provided.
func (*Transaction) HashForWitnessV0 ¶
func (tx *Transaction) HashForWitnessV0(inIndex int, prevoutScript []byte, value []byte, hashType txscript.SigHashType) [32]byte
HashForWitnessV0 returns the double sha256 hash of the serialization of the transaction following the BIP-0143 specification. This hash should then be used to produce a witness signatures for the given inIndex input.
func (*Transaction) Serialize ¶
func (tx *Transaction) Serialize() ([]byte, error)
Serialize returns the serialization of the transaction.
func (*Transaction) SerializeSize ¶
func (tx *Transaction) SerializeSize(allowWitness, forSignature bool) int
SerializeSize returns the number of bytes it would take to serialize the the transaction.
func (*Transaction) ToHex ¶
func (tx *Transaction) ToHex() (string, error)
ToHex returns the serializarion of the transaction in hex enncoding format.
func (*Transaction) TxHash ¶
func (tx *Transaction) TxHash() chainhash.Hash
TxHash generates the Hash for the transaction.
func (*Transaction) VirtualSize ¶
func (tx *Transaction) VirtualSize() int
VirtualSize returns the total weight of a transaction excluding witnesses
func (*Transaction) Weight ¶
func (tx *Transaction) Weight() int
Weight returns the total weight in bytes of the transaction
func (*Transaction) WitnessHash ¶
func (tx *Transaction) WitnessHash() chainhash.Hash
WitnessHash generates the hash of the transaction serialized according to the new witness serialization defined in BIP0141 and BIP0144. The final output is used within the Segregated Witness commitment of all the witnesses within a block. If a transaction has no witness data, then the witness hash, is the same as its txid.
type TxInput ¶
type TxInput struct {
Hash []byte
Index uint32
Sequence uint32
Script []byte
Witness TxWitness
IsPegin bool
PeginWitness TxWitness
Issuance *TxIssuance
IssuanceRangeProof []byte
InflationRangeProof []byte
}
TxInput defines an elements transaction input.
func NewTxInput ¶
NewTxInput returns a new input with given hash and index and a default max sequence number.
func (*TxInput) SerializeSize ¶
SerializeSize returns the number of bytes it would take to serialize the the transaction input.
type TxIssuance ¶
type TxIssuance struct {
AssetBlindingNonce []byte
AssetEntropy []byte
AssetAmount []byte
TokenAmount []byte
}
TxIssuance defines the type for Issuance field in TxInput
type TxOutput ¶
type TxOutput struct {
Asset []byte
Value []byte
Script []byte
Nonce []byte
RangeProof []byte
SurjectionProof []byte
}
TxOutput defines an elements transaction output.
func NewTxOutput ¶
NewTxOutput returns a new output with given asset, value and script and a default 0 nonce.
func (*TxOutput) SerializeSize ¶
SerializeSize returns the number of bytes it would take to serialize the the transaction output.
type TxWitness ¶
type TxWitness [][]byte
TxWitness defines the witness for a TxIn. A witness is to be interpreted as a slice of byte slices, or a stack with one or many elements.
func (TxWitness) SerializeSize ¶
SerializeSize returns the number of bytes it would take to serialize the the transaction input's witness.
